Nadia 1999 model Incorrect fuel level indication

Could be the temperature sensor.

There should be 2 level adjusters on the front of the fridge, adjust them to make the fridge level and take the weight off the wheels.

The high pressure fuel pump is leaking fuel past its seals into the engine oil.

The hp fuel pump is located on the valve cover.

The oil level will not rise because when the oil is contaminated with fuel, it's viscosity is affected, and it will make the engine burn more oil.

You will need to replace the High Pressure Fuel Pump, drain and fush oil and replace oil filter.

If all three pipe were connected then you can't use the one with two

fuel filter fuel pump

these Direct injection engines do carbon up the inlet ports
inlet manifold off to clean the ports

a digital gauge recieves information the same way as a mechanical/needle gauge , via the fuel pump / sender unit , the bars are leds that light up or go off with the level of fuel .

Your fuel sending unit is going bad. You're gonna have to replace it or live with it...

Check the fuel pressure when it stops ,could be a faulty fuel pump or even more so a faulty connection plug on the top of the fuel pump gauge sender unit

Hi, The 1999 blazer has a fuel level sensor mounted in the fuel tank. It is mounted to the module that contains the electric fuel pump. The tank must be removed in order to service this module assy. When the level sensor is faulty, it can cause the guage to read erratic, or incorrect. If the computer senses a fault with the sensor, the check engine light can come on, and the fuel guage can drop to empty. A code can set for the fuel level, and this sensor can be replaced seperate. Good luck... Coop

DTC P1209 indicates that injection control pressure was above or below desired level under normal driving conditions.

Possible causes:

1. Incorrect oil or viscosity
2. Poor oil quality
3. Gel fuel/no fuel
4. Low fuel pressure
5. Damaged IPR valve
6. High-pressure oil system leak
7. Damaged high-pressure oil pump
8. Damaged PCM
9. Verify correct oil quality/viscosity and correct fuel grade are being used for the temperature conditions.
